Trigeminal neuralgia (TN, or TGN), also known as prosopalgia, tic doloureux, or Fothergill's disease is a neuropathic disorder characterized by episodes of intense pain in the face. It has been described as among the most painful conditions known. The pain originates from a variety of different locations on the face and may be felt in front of the ear, eye, lips, nose, scalp, forehead, cheeks, mouth, or jaw and side of the face. Although there is general agreement that none of the many existing theories fully explain all known characteristics of TGN pain the bulk of current evidence points to the trigeminal nerve rather than the CNS as the site of generation of TGN pain. More specifically, the existing evidence suggests that a slowly evolving process, whether a compression exerted on the nerve by a blood vessel or tumour or alteration of neural functions by an MS plaque at the level of the dorsal root entry zone, leads to increased excitability in some of the trigeminal afferents and subsequently to typical TGN. Transcranial magnetic stimulation appears promising, but results are still scarce. Adjunct treatments such as mechanical, electrical, and thermal stimuli sometimes modify pain with fewer adverse effects than medication. Self-adhesive bandages may also be used. France people around 1,887,252 among the total population are suffering from this disease that is 4.88% of the population effected.
